AMD Threadripper Pro 9995WX Overclocked to 5.3 GHz Using Advanced Liquid Cooling Setup

• February 6, 2026

A Chinese YouTube channel, Geekerwan, has achieved a remarkable feat by overclocking AMD’s Threadripper Pro 9995WX processor to 5.3 GHz without the use of liquid nitrogen. This 96-core workstation CPU, which typically carries a significant price tag, was subjected to an intense and carefully engineered cooling solution to maintain stability at these high clock speeds.

Custom Liquid Cooling Enables Extreme Overclocking

The extreme overclocking challenge involved completely transforming the CPU’s cooling approach. Instead of relying on conventional air or standard liquid cooling setups, the heat spreader atop the processor was replaced with a custom-manufactured integrated heat spreader (IHS) that doubles as a waterblock. This IHS was precision-machined using CNC equipment to optimize thermal conductivity and facilitate direct liquid cooling of the CPU die.

To handle the tremendous heat output from the 96-core chip running beyond its typical operational frequencies, the cooling system incorporated automotive-grade liquid cooling components. An industrial chiller was employed to maintain low coolant temperatures consistently, supported by an extensive reservoir capacity—approximately 140 liters of coolant circulation—to ensure stable and effective heat dissipation.

This elaborate setup not only successfully pushed the CPU frequency to 5.3 GHz but also avoided more extreme cooling methods like sub-zero liquid nitrogen, which while effective, are less practical for sustained use and carry higher risks.

The AMD Threadripper Pro 9995WX, targeted primarily at professional workstations, features an abundance of cores and threads designed for high-performance computing workloads. Achieving stable overclocking at such speeds on a processor with this core count presents significant technical challenges, especially due to the substantial thermal load generated under heavy use.

By embedding a waterblock into the processor’s heat spreader and combining it with a high-capacity cooling loop and industrial chilling, the demonstration highlights innovative approaches to cooling large-scale workstation processors beyond conventional methods. Such modifications can extend performance envelopes considerably, providing insights into the thermal management strategies needed as CPU core counts and power consumption continue to rise.

While the specific operational conditions, duration, and workload scenarios during the overclocking tests were not detailed, the feat underscores the growing interest and technical capability in extreme workstation CPU overclocking using specialized liquid cooling infrastructures.

Overall, this achievement by Geekerwan showcases the potential for advanced custom cooling solutions to unlock additional performance in high-end workstation CPUs, offering enthusiasts and professionals alike a glimpse into the future of processor overclocking.
